1. Can you pl point me to what chmod -H should do?

2. Creation of an symlink log shows up this way in the audit log:

ugi=dhruba,users,engineers,svnuser	ip=/1.2.3.4	cmd=createSymlink	src=/user/dhruba/foo	dst=../test1
perm=dhruba:none:rw-rw-rw-

> HDFS should support symbolic links. A symbolic link is a special type of file that contains
a reference to another file or directory in the form of an absolute or relative path and that
affects pathname resolution. Programs which read or write to files named by a symbolic link
will behave as if operating directly on the target file. However, archiving utilities can
handle symbolic links specially and manipulate them directly.
